Hi everyone,

I'm facing an issue with payment grouping in Odoo 18 (and apparently also in 18.1) when trying to group SEPA Direct Debit (SDD) payments.

Even though the option to group payments is still available for SDD, it does not work. After reaching out to support, I was told that this is the "expected behavior," which is quite frustrating, especially considering the following:

1. The option to group payments is still available for SDD in V18, but it does nothing.
2. In Odoo 17.4, the same option worked correctly, grouping payments for SDD as expected.
3. Batch payments for both customers and vendors still work correctly in Odoo 18, just as they did in the previous version.

To me, this looks like a bug introduced in the V18 update, rather than an intentional change.

Has anyone else encountered this issue? Is there any workaround, or should this be reported as a bug?

Thanks in advance for your insights!
